TECHNICAL FIELD

This disclosure relates to undergarments, for example, undergarments or underwear for males.

BACKGROUND

Undergarments exist in a number of forms, such as boxer shorts, briefs, the combination boxer brief, baselayer or thermal long underwear, and other undergarment types for males. Each style provides a different combination of fit, comfort, and support.

SUMMARY

This disclosure describes undergarments, particularly undergarments for males.

In some aspects, an undergarment includes a body having a substantially tubular shape and configured to at least partially surround a torso of a user. The body includes a pouch portion about a front surface of the body, and a gusset portion. The pouch portion is connected to a body panel at lateral sides of the pouch portion, the pouch portion having a rounded bottom periphery at a first, lower longitudinal end of the pouch portion to form a U-shaped periphery of the pouch portion. The gusset portion at least partially borders the rounded bottom periphery of the pouch portion.

This, and other aspects, can include one or more of the following features. The pouch portion can include lateral side seams connecting the pouch portion to the body panel at the lateral sides of the pouch portion, and a curved bottom seam along the rounded bottom periphery, the curved bottom seam connecting the pouch portion to the gusset portion. A transition from the curved bottom seam to the lateral side seams can be continuous and can include a gradual change in curvature between the curved bottom seam and the lateral side seams. The gusset portion can include gusset side seams at a front portion of the gusset portion that extend from the pouch portion to a lower longitudinal end of the body, where the gusset side seams connect to the pouch portion at an intersection of the lateral side seams and the curved bottom seam of the pouch portion. A first, longitudinally lower width of the pouch portion between upper ends of the rounded bottom periphery can be greater than a second, longitudinally higher width of the pouch portion between the lateral sides of the pouch portion in an upper longitudinal half of the pouch portion. The curved bottom seam of the pouch portion can include lock stitching along at least a portion of a length of the curved bottom seam. The curved bottom seam can include the lock stitching along an entire length of the curved bottom seam. The pouch portion can include a center seam extending longitudinally from the first, lower longitudinal end to a second, upper longitudinal end of the pouch portion. The pouch portion can include a fly opening. The body can include a first leg portion and a second leg portion substantially parallel to the first leg portion, the first and second leg portions extending toward a first longitudinal end of the body. The undergarment can include a waistband attached to the body at a second longitudinal end of the body opposite the first longitudinal end. The gusset portion can be sewn at least partially along gaps in the first leg portion and second leg portion. The undergarment can be a boxer brief. The pouch portion, the body panel, and the gusset portion can be formed from fabric comprising at least 5% spandex.

Certain aspects of the disclosure encompass a method for making an undergarment. The method includes forming a pouch portion of an undergarment, the pouch portion comprising a U-shaped periphery having a rounded bottom periphery at a first, lower longitudinal end of the pouch portion, connecting the pouch portion to a gusset portion with a curved bottom seam at least partially along the rounded bottom periphery of the pouch portion, and connecting the pouch portion to a body panel of the undergarment along lateral side seams of the pouch portion, the lateral side seams extending from lateral ends of the curved bottom seam.

This, and other aspects, can include one or more of the following features. The method can include connecting gusset side seams of the gusset portion to the body portion, the gusset side seams disposed at a front portion of the gusset portion and extending from the pouch portion to a lower longitudinal end of the undergarment, the gusset side seams connected to the pouch portion at an intersection of the lateral side seams and the curved bottom seam of the pouch portion. A transition from the curved bottom seam to the lateral side seams of the pouch portion can be continuous and can include a gradual change in curvature between the curved bottom seam and the lateral side seams. Connecting the pouch portion to the gusset portion with the curved bottom seam can include connecting the pouch portion to the gusset portion with lock stitching at least partially along the rounded bottom periphery of the pouch portion.

In some aspects, an undergarment includes a body having a substantially tubular shape and configured to at least partially surround a torso of a user. The body includes a pouch portion about a front surface of the body, the pouch portion including a U-shaped periphery having a rounded bottom periphery at a first, lower longitudinal end of the pouch portion, and a gusset portion at least partially bordering the rounded bottom periphery of the pouch portion. The gusset portion includes gusset side seams at a front portion of the gusset portion extending from lateral ends of the rounded bottom periphery of the pouch portion to a lower longitudinal end of the body.

This, and other aspects, can include one or more of the following features. The pouch portion can connect to a body panel at lateral sides of the pouch portion. The gusset portion can connect to the body panel at the gusset side seams.

The details of one or more implementations of the subject matter described in this disclosure are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

This disclosure describes undergarments for males (e.g., men and boys), for example, undergarments to support a male anatomy during movement (e.g., everyday activity, exercise, and/or other) of a user of the undergarment. An example undergarment includes a front pouch portion and a gusset portion that allow for flexibility and comfort to a wearer of the undergarment. The front pouch portion has a U-shaped periphery with a rounded bottom periphery portion, and the front pouch portion is slightly wider near a bottom of the pouch than a top of the pouch. The gusset portion lines the rounded bottom periphery portion of the U-shaped periphery at the bottom of the pouch portion, where a sewn seam connecting the gusset portion and the pouch portion can include lock stitching. The 3D convex shaped pouch with U-shaped pouch periphery and connected shaped gusset provide more comfort for the wearer, for example, because the U-shape of the pouch more naturally surrounds and supports the male anatomy of the wearer, and provides a more ergonomic, customized fit that conforms to the body shape of the wearer. In some instances, the U-shaped pouch extends lower on the body of the wearer than conventional undergarment pouches, for example, to provide additional room for the male anatomy of the wearer and an ergonomic design of the pouch and gusset. In some examples, an undergarment with the disclosed pouch and gusset reduce a risk of chafing of the wearer by reducing friction between the male anatomy of the wearer and the body. For example, the convex pouch and U-shaped periphery forms a fabric barrier, increasing comfort and gives the support of a brief.

FIG. 1 is a front perspective view of an example undergarment 100, and FIGS. 2 and 3 are a front view and a rear view, respectively, of the example undergarment 100. The undergarment is shown as a mid-thigh boxer brief style undergarment. However, the example undergarment 100 can take on a variety of styles, such as briefs, boxers, trunks, low-thigh underwear, baselayer or thermal long underwear, a liner for swimwear or running shorts, and/or other undergarment types. The example undergarment 100 includes a body 102 having a substantially tubular shape that surrounds, partially or completely, a torso of a wearer of the undergarment 100 at a first, upper longitudinal end 104 of the body 102. The example undergarment 100 also includes a waistband 108 connected to (e.g., adhered, sewn, integral with, and/or otherwise coupled to) the body 102 at the first, upper longitudinal end 104. In some examples, the waistband can include a covered elastic, or a turned-back self-fabric waistband that is an extension of the body 102. The body 102 forms leg portions 110 at a second, lower longitudinal end 106 of the body 102 opposite the first longitudinal end 104. In the present disclosure, a longitudinal direction is defined as a direction extending substantially between the first longitudinal end 104 and the second longitudinal end 106 of the body 102 (i.e., between the waistband 108 and the leg portions 110 along the body 102). Similarly, a lateral direction is defined as a direction extending substantially perpendicular to the longitudinal direction along, or tangential to, a surface of the body 102. FIGS. 4A and 4B are a left side view and a right side view of the example undergarment 100, and FIGS. 5A and 5B are a top view and a bottom view of the example undergarment 100.

The body 102 of the example undergarment 100 is formed from fabric portions coupled together to form the shape of the body 102. Referring to the example undergarment 100 of FIGS. 1-5B, the body 102 includes a pouch portion 112, a body panel 114, and a gusset portion 116. With a wearer wearing the undergarment 100, the pouch portion 112 is disposed adjacent to the male anatomy of the wearer, the gusset portion 116 is disposed at a crotch area of the wearer and at inner thigh portions of the legs of the wearer, and the body panel 114 forms the remainder of the body 102 and is disposed adjacent the upper legs (e.g., front, side, and rear thigh), buttocks, and sides of the torso of the wearer.

The pouch portion 112 of the example undergarment 100 is configured to be adjacent to the male anatomy of a wearer, The pouch portion 112 is a generally U-shaped panel disposed about a front surface of the body 102, where the pouch portion 112 connects to the body panel 114 of the body 102 at lateral sides (e.g., left lateral side 118 a and right lateral side 118 b) of the pouch portion 112. The pouch portion 112 is substantially symmetrical across a centerline extending longitudinally along the pouch portion 112 through a lateral center of the pouch portion 112. The pouch portion 112 has a rounded bottom periphery 120 at a lateral center and at a first longitudinal end of the pouch portion 112, shown in FIGS. 1 and 2 as the lower longitudinal end of the pouch 112. The rounded bottom periphery 120 forms the rounded, curved bottom of the U-shape of the pouch 112. In the example undergarment 100 of FIGS. 1-5B, the rounded bottom periphery 120 is semicircular, having a constant radius of curvature along at least a portion of (e.g., most of or all of) the length of the rounded bottom periphery 120. In some implementations, the rounded bottom periphery 120 can have a shape that is semicircular, semi-elliptical, parabolic, oval, arced (e.g., having a circular arc shape or elliptical arc shape between 20 degrees and 180 degrees), or another rounded shape. FIGS. 6A and 6B are a schematic front view and a schematic rear view, respectively, of the example undergarment 100. FIG. 6A includes labeled reference lengths A, B, C, and D, where A represents the lateral radius of the rounded bottom periphery 120, B represents the longitudinal radius of the rounded bottom periphery 120, C represents the curved length of the rounded bottom periphery 120, and D is the length of the fabric of the pouch 112 between approximate ends of the rounded bottom periphery 120. The lengths A and B can be the same or different. In some examples, the difference between radius B and radius A can range from 80% to 120%, where 80% means that lateral radius A is 80% of the length of longitudinal radius B, where 100% means that A and B are equal length (and the rounded bottom periphery 120 has a constant radius of curvature), and 120% means that lateral radius A is 120% of the length of longitudinal radius B. In certain examples, the length D can range from a minimum distance of 100% length (e.g., where the pouch 112 is flat and the distance D is represented by a straight line of fabric generally between ends of the rounded bottom periphery 120) up to 250% (e.g., where the pouch 112 is convex outward and the distance D is represented by a curved line of fabric with a length of 250% of the minimum length). For example, the outwardly convex shape of the pouch portion 112 can provide an outward protrusion of the pouch portion 112. The outward protrusion can vary in size, for example, between zero inches and one inch, such as 0.9 inches for a men's medium size boxer short.

The rounded bottom periphery 120 of the pouch portion 112 of the example undergarment 100 has a rounded shape that is continuous with the left lateral side 118 a and right lateral side 118 b of the pouch 112, which forms the U-shaped periphery of the pouch portion 112. In other words, the left lateral side 118 a, rounded bottom periphery 120, and right lateral side 118 b of the pouch 112 form a partial periphery of the pouch 112 that is continuous and has gradual change in curvature along the length of the periphery. The remainder of the periphery (e.g., other than the U-shaped partial periphery) of the pouch portion 112 borders the waistband 108. The partial periphery excludes acute angled transitions between the rounded bottom periphery 120 and the lateral sides 118 a and 118 b, and excludes acute discontinuities along the length of the rounded bottom periphery 120. For example, the transition between the bottom periphery 120 and the lateral sides 118 a and 118 b is continuous and gradual, where the rounded shape of the bottom periphery 120 gradually transitions (e.g., the radius of curvature gradually increases) to the shape (e.g., a curve or straight line) of the lateral sides 118 a and 118 b. The lateral sides 118 a and 118 b have a lesser degree of curvature than (e.g., a greater radius of curvature than) the rounded bottom periphery 120. In certain examples, the lateral sides 118 a and 118 b are substantially straight, where the U-shaped periphery of the pouch 112 has a radius of curvature that transitions from the sharper curve (e.g., smaller radius of curvature) of the rounded bottom periphery 120 to the straighter line or straighter curve (e.g., larger radius of curvature) of the lateral sides 118 a and 118 b.

In some implementations, the transition between the rounded bottom periphery 120 and the lateral sides 118 a and 118 b is defined by the point along the periphery of the pouch portion 112 where the radius of curvature changes. For example, the rounded bottom periphery 120 can include a semicircular shape with a constant or substantially constant radius of curvature along its length, as described earlier. The transition points can be defined as the ends of the rounded bottom periphery 120 where the radius of curvature increases from the radius of curvature of the semicircular shape (or other curved shape) toward the radius of curvature of the lateral sides 118 a and 118 b. The length of the rounded bottom periphery 120 can vary. For example, the rounded bottom periphery can have a length along its curve of between two inches and eight inches, such as six inches. In some implementations, the length of the rounded bottom periphery 120 (indicated in FIG. 6A as length “C”) is between 24 percent (%) and 38% of the total U-shape periphery of the pouch portion 112 (e.g., from waistband point of left lateral side 118 a to waistband point of right lateral side 118 b). For example, the length of the rounded bottom periphery 120 can be about a third of (e.g., about 33% of) the total length of the U-shape periphery of the pouch 112.

The lateral sides 118 a and 118 b of the pouch portion 112 of the example undergarment 100 can take a variety of shapes. In FIG. 2, the lateral sides 118 a and 118 b are shown with a slight curve such that the lateral sides 118 a and 118 b curve inwardly toward the lateral center of the pouch portion 112 as the lateral sides 118 a and 118 b extend toward a second, upper longitudinal end of the pouch portion 112 (e.g., toward upper longitudinal end 104 of the body 102). However, the shape of the lateral sides 118 a and 118 b can be different. For example, the lateral sides 118 a and 118 b can be linear between ends of the rounded bottom periphery 120 and the upper longitudinal end 104 of the body 102 (i.e., at the waistband 108), can include a sharper curve along the length of the lateral sides 118 a and 118 b than shown in the example undergarment 100 of FIG. 2, can curve outwardly away from a lateral center of the pouch portion 112, or can take on different shapes.

In some implementations, a lateral width of the pouch portion 112 decreases from the transition point between ends the rounded bottom periphery 120 and the lateral sides 118 a and 118 b to the upper longitudinal end of the pouch portion 112. For example, a first lateral width of the pouch portion 112 in a longitudinally lower half of the pouch portion 112, such as the lateral width between upper ends of the rounded bottom periphery 120, is greater than a second lateral width of the pouch portion 112 in a longitudinally upper half of the pouch portion 112, where the lateral width is measured between the lateral sides 118 a and 118 b of the pouch portion 112. The shape of the pouch portion 112, such as having a lower lateral width that is greater than an upper lateral width, can provide enhanced fit and comfort to a wearer of the undergarment, as described in more detail later.

Lateral side seams (i.e., left lateral side seam 119 a and right lateral side seam 119 b) connect the lateral sides 118 a and 118 b of the pouch portion 112 of the example undergarment 100 to the body panel 114. The body panel 114 extends from the left lateral side 118 a of the pouch 112 laterally along the body 102 to a rear of the body 102, and further extends back around to the front surface of the body 102 and to the right lateral side 118 b of the pouch 112. The body panel 114 substantially surrounds the wearer of the undergarment 100. The body panel 114 and the pouch 112, when connected together (e.g., with lateral side seams 119 a and 119 b), are configured to completely surround the wearer. In FIGS. 1 to 6B, the body panel 114 is shown as a substantially continuous fabric panel without seams or other discontinuities along its lateral length extending from the left lateral side seam 119 a around the rear of the body 102 and to the right lateral side seam 119 b. However, the body panel 114 can take a variety of forms, and can include intermittent seams, fused fabric connections, cut-and-sew fabric pieces, or other discontinuities in the body panel 114. For example, the body panel 114 can be formed of multiple fabric pieces knit together, sewn together, and/or otherwise coupled together to form the remainder of the body 102 (other than the pouch portion 112 and gusset portion 116).

The gusset portion 116 of the example undergarment 100 is a fabric panel that extends between the leg portions 110 and connects to the body panel 114 to form part of the second, lower longitudinal end 106 of the body 102. The gusset portion 116 also at least partially borders the rounded bottom periphery 120 of the pouch 112. A curved bottom seam 122 connects the pouch portion 112 to the gusset portion 116 along all or a portion of the rounded bottom periphery 120 of the pouch portion 112. The gusset portion 116 also connects to the body panel 114 with gusset side seams 124. The gusset side seams 124 are disposed at a front of the gusset portion 116, and extend from the periphery of the pouch portion 112 to the lower longitudinal end 106 of the body 102. In some implementations, the gusset side seams 124 connect to the pouch portion 112 at the intersection of the lateral side seams 119 a and 119 b and the curved bottom seam 122.

The gusset portion 116 also includes a rear seam 126 that connects to the body panel 114 at a rear of the undergarment 100. The rear seam 126 is an arch shape, or upside-down U-shape. In certain instances, the gusset portion 116 connects to the body panel 114 at the gusset side seams 124 and the rear seam 126 to form the substantially cylindrical, tubular shape of the leg portions 110 at the second longitudinal end 106 of the body 102. Each of the leg portions 110 has a leg opening at the second longitudinal end 106 of the body 102, defined in part by the body panel 114 and the gusset portion 116 connected together by the side seams 124 and the rear seam 126. The gusset portion 116 has an ergonomic shape between the leg openings, for example, to better fit the curved shape of the body of the wearer of the undergarment 100. The gusset side seams 124 are disposed and extend more laterally outward from a lateral center of the undergarment 100 than the rear seam 126. In some instances, a front area of the gusset portion 116 (e.g., the portion of the gusset portion 116 on the front half of the undergarment 100) is greater than a rear area of the gusset portion 116 (e.g., the portion of the gusset portion 116 on the rear half of the undergarment 100).

The example undergarment 100 can be used by male wearers. As such, the pouch portion 112 can be configured to receive and support the male anatomy of the wearer. In some instances, the curved bottom seam 122 includes extra lock stitching, for example, to provide a more robust connection between the pouch portion 112 and the gusset portion 116 and to provide additional support under the male anatomy of a wearer when the undergarment 100 is being worn by the wearer. In some instances, the lock stitching reduces or restricts stretch in the bottom seam 122 to stabilize the bottom seam 122, and/or reduces or restricts movement in the bottom of the pouch portion 112 or the gusset portion 116 (or both) proximate to the curved bottom seam 122 to add further support under the male anatomy of the wearer of the undergarment 100. The lock stitching can extend along a portion of or the entirety of the length of the curved bottom seam 122, for example, between the gusset side seams 124.

In some implementations, the pouch portion 112 of the example undergarment 100 includes a fly opening 128. The fly opening 128 can be formed by a partial overlap of two pieces of fabric that make up the pouch portion 112. In other implementations, the fly opening 128 can be excluded, and the pouch portion 112 can be formed of one or more fabric panels extending from the left lateral side 118 a to the right lateral side 118 b of the pouch portion 112 without an opening.

The pouch portion 112 of the example undergarment 100 is configured to form an outwardly extending convex shape, which forms a pouch-like pocket to hold and support the male anatomy of a wearer of the undergarment 100. In some implementations, the pouch portion 112 includes a center seam 130 extending longitudinally along the pouch portion 112 at a lateral center of the pouch portion 112. The center seam 130 extends longitudinally from the first, lower longitudinal end of the pouch portion 112 to the second, upper longitudinal end of the pouch portion 112. The center seam 130 can bias the pouch portion 112 to create and maintain its convex shape, and in some instances, can provide additional support and strength to the pouch portion 112. For example, some implementations of the pouch portion 112 include two conversely curving pouch pattern pieces sewn together with the center seam 130, and the center seam 130 can promote the 3D, convex shape of the pouch portion 112 from the two curving pouch pieces. In some implementations, the center seam 130 can include (or be replaced with) a dart, or the pouch 112 can exclude the center seam altogether. The shape of the pouch portion 112, such as having a lower lateral width that is greater than an upper lateral width, can provide enhanced fit and comfort to a wearer of the undergarment. For example, the wider bottom portion of the pouch 112 in conjunction with the curved, convex shape of the pouch 112 and the center seam 130 creates a 3D pouch shape to hold the male anatomy. As the pouch 112 is filled or formed by the male anatomy of a wearer, the lateral side seams 119 a and 119 b straighten, which can help position the fly opening 128 in a position for functional fly use.

The body 102 of example undergarment 100 can be formed from a number of different materials and fabrics, such as elastomeric or stretch knitted fabric. Such fabrics can be made by varying combinations of cotton, polyester, nylon, spandex, viscose, modal, lyocel, and/or rayon fiber yarns, for example, to provide softness, comfort, and desired stretch properties. The fabrics can be knit in a variety of knit types, such as jersey, rib, mesh, and/or other knit textures and structures. For example, the body 102 of example undergarment 100 can be formed from stretch fabric having no less than 1% spandex (for example, at least 5% spandex) to provide flexibility to the fabric and comfort to the wearer. In some implementations, the fabric is a knit fabric having a mechanical stretch to provide a factor of stretchability to the fabric. Mechanical stretch can be defined as a knitting structure of a fabric that creates extra give through the gauge of the knitting, through texture (e.g., a rib structure), or both. For example, a fabric knit with a fine rib pattern can provide mechanical stretch to the fabric.

FIG. 7 is a flowchart describing an example method 200 of making an undergarment, for example, the example undergarment 100 of FIGS. 1-6B. At 202, a pouch portion of an undergarment is formed, where the pouch portion has a rounded, U-shaped periphery at a first, lower longitudinal end of the pouch portion. At 204, the pouch portion is connected to a gusset portion with a curved bottom seam at least partially along the U-shaped periphery of the pouch portion. At 206, the pouch portion is connected to a body panel of the undergarment along lateral side seams of the pouch portion, the lateral side seams extending from lateral ends of the curved bottom seam. The order of construction of the undergarment can vary. In some implementations, the undergarment 100 can be formed by first constructing the pouch portion 112 (e.g., sewing fabric panels together at center seam 130 to form the pouch portion 112), then attaching the gusset portion 116 to the body panel 114 at the front of the leg portions 110 (e.g., at the gusset side seams 124), then attaching the pouch portion 112 to the body panel 114 and the gusset portion 116, optionally lock-stitching the curved bottom seam 122 at the rounded bottom periphery 120, and then sewing the gusset 116 to the body panel 114 at the rear of the garment (e.g., at rear gusset seam 126).

A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure.
